Pricing

Course views, not seats.

Everyone else in this category quotes you privately and charges per active learner. We publish the number and charge for course views — so the four hundred people who never opened it cost you nothing.

One course view

A learner opens a course and reaches the first screen. Everything after that — every screen, every replay, every certificate — is the same one view.

Coming back doesn't recount

The same learner returning to the same course inside 30 days is still that one view. Resuming is not a new view. That needs the embed to carry a signed identity — it's how we know it's the same learner. Without one, every open counts.

Nobody counts twice

No seat licences, no “active user” maths, no charge for the four hundred people your LMS enrolled who never opened anything.

Overage bills monthly in arrears at your plan's rate. The billing page warns you at 80%. Nothing throttles, nothing switches off, no course stops loading half way through a lesson.

The part they won't put on a page

Why nobody else shows you a number.

We went looking for what the customer-education platforms actually charge. None of them publish it. Here is what buyers report paying, from public review sites and procurement disclosures.

Enterprise customer-education platforms$18,000 – $90,000+
Active learners, tieredNo — quote only
Enterprise LMS suitesfrom ~$25,000
Seats, annual commitNo — quote only
Mid-market LMS, active-user plans$1,400 – $5,400
Active users per monthYes
Creator course platforms$290 – $1,200
Flat, revenue share on someYes
Underlayer$1,490 – $18,000
Course viewsYes — it's above

Ranges are what buyers report on public review and procurement sites, not vendor list prices — there aren't any. Underlayer's figure is Build through Enterprise at the yearly rate, before overage. We'll keep this table honest; if a number here is wrong, tell us and we'll fix it.

Questions we'd ask.

What happens when I go over?

The billing page warns you at 80% and again once you pass 100%. Then extra views bill at your plan's rate at the end of the month. Nothing throttles and no learner is turned away mid-course — cutting someone off half way through a compliance module is not a billing strategy.

Can I switch plans mid-month?

Up or down, instantly and prorated: an upgrade charges the difference now, a downgrade becomes a credit on your next invoice. No call, no retention queue — it's a button on the billing page.

What if my volume is seasonal?

That's the point of paying for views. A quiet quarter costs you a quiet quarter. Nobody makes you buy seats for a peak you hit once a year.

Do you take a cut if I sell courses?

No. Never. If you charge for your course, that's between you and your learners.

Is there a discount?

50% off Build and Scale for registered non-profits and schools. Yearly is two months free, already shown above.

What happens to my content if I leave?

Export everything — courses as JSON, SCORM packages, learner records as CSV — on any plan including the free one. It's your content. We host it, we don't hold it.
